Now that I remember it I passed in front of that particular shop in Takeshita! I remember how excited I was seeing all those idol ahops. I stopped a little but I would lose the others in my group (which constantly got on my nerves with their complete lack of knowledge on modern Japanese culture and their Arashi hate-speech) so I left without going in. Next time however I'm going in and I'm buing a ticket however much it costs! Hah!
